In the illustratedembodiment of the invention, the severalviews-show afilling machine 10, comprising aitable. H- of suitable width to-accom modate the largest, size mattress. The table ll is mounted on.a front frame l2 and a-rear frame I3... Upright side members I 4 are mounted on thetable ll and-are. hinged-by pivot pins ill to end wall-extensions I6 of movable spout members ll; The sidemembers l lare supportedat their free rear. endsfrom the upper. surface lElof the rear frame I3.-.by means of. angularly bent rods H]. The side members Mandthe movable spout members H arethus jointly adjustable over the table II according to the. width of the mattress. cover or the like tobe filled.

As bestshown inEig. 4,- the vertical end walls 20 of the movablespoutmembers I! are integral and. in. right angular. relation with lower horizontal walls. 2|. The. horizontal walls 2!. are provided at: their. rear endswithdownwardly ex.- tendingflangesZL The lower ends of the flanges 22. are bent. to. provide upwardly extendingportions-23. whichengage with the lower edge of a cross-bar 24. The cross-bar 24 is fixedto'the uprightsZ-E, 25 of the frame [2. The cross-bar 40 2.4servesto maintain the lower. spout members H in slidable horizontal position. Right angular upper. movable spout..members 2.6.slmilar to the lower movable spout members H,. are positioned above the spout members ll. andare provided at theirrear ends with. upwardly extending flanges 21,. Theupper ends of. the fianges 2'! are bent to provide. downwardly, extending portions 28. which engage the upper edgeof anangle iron 29. The spout members .26v comprise vertical end walls 31 which areintegral and in rightangular relation with. respect to the upper horizontallwalls 32-. The. angle. iron. 29'. extends transversely of the. machine. and its opposite ends arefastened respectively to. endplates. 30.. The angle iron 29 serves to maintain the upper spout members 26 in slidable horizontal position.

The movable spout members IT and 26 are respectively in telescoping relation with lower horizontal plates 33 fixed to the cross-bar 24 and upper horizontal plates 34 fixed to the angle iron 29. One of the fixed plates 34 is provided with a hinged flap 35 which may be swung down as shown in Figure 4, to complete the formation of a rectangular spout 35. Similarly, one of the fixed plates 33 is provided with a hinged flap 31 which may be swung up to complete the formation of a rectangular spout 36. As shown in Figure '7, the flaps 35 and 31 may be swung into horizontal position and form a single rectangular spout 38 which may extend substantially the full width of the table I I. It Will be understood that means is employed to provide the machine with a single filling spout for filling relatively large mattress covers, ticks or the like, and also to provide a plurality of filling spouts for simultaneously filling a plurality of covers, etc.

As best shown in Figures 2 and 3, plates 39 are mounted in overlapping relation with plates 49 on the table H, between the side members l4. The plates 39 and 43 are provided with pins 41 which are adapted to enter into apertures 42 in a cross-bar 43. The plates 39 and 40 and crossbar 43 are slidably mounted upon the table II. A plurality of spring prongs 44 are secured to the upper surfaces of the plates 39 and 43. The prongs 44 on the plates 39 and 43 extend upwardly and forwardly toward the front or spout end of the machine.

As best shown in Figure 1, angle members 45 and channel members 46 are fastened to the lower plates 43 and form receiving means for a pusherbar 41 extending transversely of the table I l. The pusher-bar 41 is adapted to operated in conjunc tion with the wide spout 38 shown in Figure 7. The spout 38 is designed for filling mattress covers of a width corresponding to the maximum width of the table I I. The spout arrangement 36 and 35 shown in Figures 2 and 4 is designed for filling simultaneously two narrow mattress covers.

Sprocket chains 48 are mounted on sprocket gears 43 on shafts 53 at opposite ends of the machine. The shafts 58 extend transversely of the machine and are supported by the frames I2 and I3. The upper portions of the chains 48 slide on the table i l. The cross-bar 43 is fastened at both ends to the sprocket chains 48. As shown in Figures 5 and 6, a motor 5| has a pinion gear 52 on its shaft in mesh with a gear 53 which is fixed to one of the sprocket chain shafts 55. The motor thus connected serves to drive the sprocket chains 48, which in turn, by virtue of the cross bar 43, move the pusher-bar 41, and the pronged plates 39 and 40, so as to cause a batch of filling material placed on the pronged plates to be carried into the narrow spouts 35 and 36 or to the wide spout 38.

Mounted in suitable bearings in the end plates 30 is a feed and compression roller 54 designed to bear upon and compress the filling material carried by the pronged plates 39 and 49, and also to push the filling material through the spout. As shown in Figure 1, the roller 54 is provided with prongs 55 projecting radially therefrom. The prongs 55 serve to grip and compress the filling material down to the height to which the spout has been set. The prongs 55 also augment the movement of the filling material through the spout. The roller 54 must be vertically adjustable in order to vary the space between the roller and the bottom of the spout and thus control the thickness of the filling material so as to adapt the machine for making mattresses of different thicknesses. This vertical adjustment is effected by supporting the end plates 33 from a trans- Verse shaft 53 by means of links 5'! and 58 and by providing a worm gear 5?) and a worm as for actuating the shaft 53. The shaft as is supported by the uprights 25 and 25 of the frame 22. The

links 5? are fixed to the shaft 5-3 and are pivotally connected with the links 53 respectively, and the links 53 are pivotally connected wlth the plates 39 respectively. The gear 59 is secured to the shaft 56 and the worm 39 which meshes with the gear 59 is secured to a shaft 54. The uprights 25, 25 of the front frame l2 are provided with vertical, oblong slots 6| forming guides for oblong members 52 fastened to the end plates 33. Inasmuch as the upper spout members 23 and 34 are supported from the angle iron 29 which is fastened to the end plates 33, the said spout members as well as the roller 54 are supported from the shaft 55. The operator may, by rotating a hand wheel 63 on the shaft 34, raise or lower the roller 54 and the upper members of the spout s simultaneously.

The roller 54 is mounted on a shaft 65 supported by the members 52, and is driven from a sprocket pinion 63 on one of the transverse shafts 53, by means of a sprocket chain 31 and a sprocket pin-- ion 68 mounted on a shaft 69. The shaft 69 is supported by bearings in parallel plates 73 mounted to swing on the shaft 65. A pinion gear H on the shaft 69 meshes with a gear 12 on the shaft 65. Motion is transmitted from the sprocket chains 48 to the roller shaft 65 through the intervention of the pinions 35 and 38, chain 37 and gears H and 12. A supporting link 13 having bearings for the shafts 53 and 69 serves in cooperation with the plates Hi to constrain the pinion gear H to remain in mesh with the gear 12 in any of the vertical positions that the gear 12 is adjusted by rotation of the hand wheel 33. It will thus be noted that the roller 54 is at all times driven in unison with the sprocket chains 48 and the pronged plates 39 and 43.

As shown in Figure l, the sprocket chains 48 have end portions 14 extended vertically. Link members 15 are mounted on plvotes 16 on the sprocket chains 48 and are respectively provided with hooks H at the free ends. Each link member 15 is provided with a counterweight l8 beyond the pivot 16. The link members 75 are constrained to follow the movements of the sprocket chains from a vertical inactive position to a horizontal operative position. It will thus be noted that when the sprocket wheels 49 are r0- tated a portion of the circumference, so as to cause the vertical end portions 14 of the sprocket chain 48 to ride, the link member 15 will rise and swing down into engagement with the channels 46 and will move horizontally with the pusherbar 47. It will be observed that as the pusherbar 41 passes beyond the roller 54, the pronged plates 39 and 40 will rest upon the lower inner surfaces of the spout. The pins 4! of the crossbar 43 becomes disengaged from the apertures 42 in the pronged plates 39 and 43, and the cross-, bar 43 being connected to the chains 43 follows the chains in their movement under the operating table II. The link members '55 being in engagement with the channels 45 will now push the pronged plates 39 and 43 through the spout. On reversing the motion of the sprocket chains, the pronged plates will be pulled out from the spout zand the .pins Al :in :the .oros-bar A'3 will become reengaged with the apertures :42 :inathemronged plates :39 and Jw this reengagcment taking .place :at .the same point where they :became disengaged.

The plates .39 :and A0 are moved :rearwardly lboth by :the pins .42! and atheilink members l5. and on reaching :the .rear frame l3, where .the end portions .of ,the .chains have .been extended in right angular relation, -tthe link members 15 will follow :themovements of the saidangularchain portions, as .shown in dot and ,dash "lines, and assume a vertical position. The vertical end portions 14 function to reduce the length of the operating table H and of :the filling machine it. It is to 15 be noted thattheangularchain portions I l-serve to lower the linkmembers 15 below the operating table H. Thesaid portions M mayhowever be dispensed .withand the link members :15 will then assume ,a vertical upright position above the table when reaching the rear :frame I3.

As shown in Figures 2 and 3, ;two ,longitudinal plates 19 are hinged respectively to the-plates 48 by hinges 80. When the plates or flaps '19 are set in right angular relation with the plates 40 and the flaps 3,5 and 31 of the spouts 36 and 3B are set in right angular relation with the fixed horizontal plates 33, asshownin Figure l,the fillingmachine I 0 becomes adapted for inserting two independent :mattress fillings into separate mattress covers simultaneously. When the flaps T9 .are swung,down into horizontal position and the spout flaps and 31 ,are swung horizontally to .theposition-shownin Figures '7 and 8, the filling ,machine It becomes adapted ior filling one wide 3'5- mattress cover extending the-entire distance between the uprightside members l l.

As shown in Figure .8, rack and-gear mechanism may be used to close up the slidable end membersof the spout and to compress the filling i0 material contained therein so as to permit the mattress cover ,to be easilyplaced over the spout. A plate 8| is suitably fastened to the uprights 2,5 25' of theiiront frame |,2.and is provided with rack ,teeth 8 2 adj acent .theslidable end .members 15 20 of ,the spout. .Gearsegments 83 are rotatably mounted in movable .members 34 which are fastened at their .lower ends to the end members ,2!) vof .thespout. Levers p85 are fixed to the gear se ments 83. ,It i thu p s i by actuating 50 the-levers ,85 to lforciblyclose up the slidableend membersfZfl of the spout. It is to be noted that the ,gear segments .83 in the position shown in Figure ,;l,,are not in engagement with the rack teeth 82 and permit ,moyement ,of the movable 55 end members of the spouts and the attached gear ,segments 83 ,over the fixed rack teeth 82. This enables the adjustment of the spout members by hand before swinging the levers 85 into engagement with the rack teeth 82 for forcibly GO bringing the end members closer together so as to permit the mattress cover to be more easily slipped over the spout.

The operation of the mattress filling machine is as follows:

65 The spout members I! and side members M are set to the width of the mattress to be filled. The filling material is placed onthe pronged plates 39 and 40 and the carrying and pushing mechanism and the roller 54 are operated to force the TO filling material through the spout into the cover arranged thereon to fill the cover. The lever 85 is swung to bring the slidable end members of the spout closer together thus compressing the filling material in the spout and reducing the width of the spout so as to permit the mattress ing materialin the spout .tojspreadiapartsideways .and :cause :the cover .-.to be :held iin iirictional .en-
